Letters Patentll o. 94,897,

dated September 14, 1869.

i IMPROVED BLACKING- roRI IARNnss-LEATHER, &c.

The Schedule referred to in these Letters Patent and making part of the same:

Be'it known that I, J UDSON N. KNAPB, of Syn-a} cuse, in the county of Onondaga, and'State of New York, haveinvented a new and improved Blacking thereof, which will enable those skilled in the art to water, so as to mix freely with the other ingredients; and by melting the spermaceti and wax in the oil, then adding the coloring-matter or lamp-black, and stirring these together.

, The soap is'then dissolved in hot water, and boiled until brought to a gummy consistency, when it is added with the molasses, and the whole well beaten together.

The gum gives body and durability to the blacking, and the sperinaceti adds to'tlie lustrejof the compound and causes the leather to retain its flexibility longer.

The wax fills the pores of the leather, so that the more volatile portions of the mixture are retained in the leather, and gives smoothness of finish.

The molasses can be omitted, but it gives body and lustre to the mixture.

The relative proportions of the ingredients may be varied somewhat, 'bnt'the proportions given are those that I have found to give the best results.

j'This combination of ingredients gives a-fine and brilliant dressing, and preserves the leather in a soft and flexible state.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

A blacking-compound, composed of the within in-v gredients, in about the proportions mentioned, substantially asset forth.

The above specification of mv invention signed by me, this 24th day of August, 1869.
